Assessment is always a roblem. Who decides what is to be tested, at what level is proficiency, etc. 

There will always be questions the computer cannot answer. Students will still need and want an energetic instructor who cares.

There are many ways that are available that may help students learn.  Adaptive learning is a way to personalize the educational experience of students with different comprehension levels.  The use of an intelligent tutor is a great way to monitor these levels.  The tutor is available 24/7 which is great for students.
